The consumption of worldwide energy use from all energy types is expected by the EIA (Energy Information Administration) - other sources come to similar figures - to increase gradually. Oil and coal remain the dominant energy type over the forecasted period. Natural gas is projected to be the fastest-growing type of energy to be consumed, reaching the level of coal by 2020. Modest growth in nuclear power will continue while the scenario for renewable energy is uncertain. Resolute plans by environmental programs could lead to an expansion in capacity of renewable energy.
